Benefits of technology

[0007]The objective of the present invention is to provide a method and a device for optimal registration of organisms in fluid by regulating the concentration and speed of flow of organisms. The invention disclosed also eliminates the need to drain water from the fish while counting which further provides a means for counting organisms without harming or upsetting them in any way. The invention provides for a non-touch method for countin...

Problems solved by technology

The high variance of concentration during counting and sorting forces manufacturers of fish counters and graders to design the inst...

Abstract

The invention comprises a method, a device and a fish-farm for controlling the concentration of living organisms in fluid in order to facilitate the handling of the organisms such as grading and counting. Said apparatus comprises a first in-feed channel for a flow of living organism in a fluid (1), a second in-feed channel for a flow of fluid (2), a chamber (4) containing a lever (11) for regulating the flow from the first and the second in-feed channel through the chamber, an outlet (15), and a computer, wherein a sensor (9) is positioned in the first in-feed channel for detecting the density of living organism in the flow, and wherein the computer continuously and automatically regulates the ratio of flow from the first and the second in-feed channel through the chamber and towards the outlet by the lever in response to the density of living organism in the flow determined by the sensor.

Description

FIELD OF THE INVENTION[0001]The invention comprises a method, a device and a system for controlling the concentration of living organisms in water in order to facilitate the handling of the organisms such as grading and counting. The invention is suited for handling live fish in fish-farming.BACKGROUND OF THE INVENTION[0002]The prior art in the field shows various devices for counting and sorting organisms in water were the object is to give the optimal registration of number and size. These devices are often limited in their capacity of processing large amounts of fish in a short time interval. The relatively unstable concentration of the fish in water, that goes through the handling systems means that they need to be designed to handle peak density. If not, the devices will not be functioning at full capacity during most of the sorting and counting process.[0003]In order to prevent overloading of the equipment, some prior art inventions have solved the problem by reducing the spee...
